Gemini 2.5 Pro Preview 05-06 is Google's near-flagship reasoning model, offering a 1-million-token context window alongside multimodal input support spanning text, images, audio, video, and files. Its intelligence index of 29.5 places it just below the top-tier frontier models, and its livecodebench score of 0.77 is among the strongest in the field. Tool use, function calling, and vision are all supported.

For businesses, this model is exceptionally well suited to long-document analysis, complex coding tasks, multimodal workflows, and agentic pipelines requiring reliable tool use. The 1M context window is a genuine competitive advantage for teams working with large codebases, lengthy contracts, or multi-document research. Its GPQA of 0.822 and HLE of 0.154 confirm strong scientific and expert-level reasoning.

At $1.25 input and $10.00 output per million tokens, output costs are high, which favours lower-output tasks such as analysis and summarisation over high-volume generation. Teams needing a capable, multimodal model with a massive context window and strong coding performance will find this a compelling option from a well-supported provider.
